My Lhasa Apso is 3 years old, and has never been to kennels. I'm looking for questions to ask to make sure he's in the best we can get so far I've got:
Are all animal boarding flea/worm treated and vaccinated?
Does he need kennel cough vaccine?
How many dogs do you exercise together?
Can he bring his own food?
How much human company will he have?
Are the sleeping areas heated?
Do dogs have access to outdoor run/indoor shelter as they want?

Any others? Had anyone had experience with companies who find a holiday home for dogs?

I'd prefer to leave him with friends, but they all have dogs/cats of their own
Meant to say, we're in UK. He normally sleeps in our room on floor and just now the back door is open, he's in the garden.

Others were:
Grooming - will they brush him if he gets caught up in grass/twigs

Feeding - what kind of schedule do they use

Do they allow us to visits to see around before we decide.
